Jell-O shots: Instead of buying plastic shot glasses, use your old K-Cups. They are the perfect size for shots — not too big and not too small!
Freeze leftover sauces: If you want to store some leftover or homemade sauces but have nowhere to put them, pour them into K-Cups, cover with plastic wrap, and put them in the freezer. What's great about using these small plastic cups is that if you make a lot of sauce, you can freeze it in small servings. That way, you can defrost just enough for one dinner.
Freeze specialty ice: Want really-cool-looking ices for your Summer cocktails? Freeze them in K-Cups! They will be bigger and have a more unique shape than ices made from a regular ice tray. Put fruits or flowers in them to make them really special. Experiment with different liquids like juices and 7UP.
Jewelry holder: If you have small pieces of jewelry lying around, then keep them organized by grouping them in little K-Cups. You can organize them by color and type.

Elevate items: Do you need help elevating items like dishes for your dinner party? Use K-Cups to raise the plates. You can also elevate things like place settings.
Place-card holder: Make your own place-card holders for parties by wrapping cute paper around K-Cups. Cut slits on the bottom to hold the cards. Your guests will marvel at your eco-savvy and craftiness!
Garden starters: Use K-Cups for seed starters. Fill one halfway with soil, dig a little hole, put some seeds in it, and cover it up. If you're growing different plants, then be sure to label them!
Garlands: Cover the K-Cups with pretty paper and string them together with some holiday lights. For inspiration, check out this post on how to make garland made from Dixie cups.
